niachine, shown in the present instance as a Victor phonograph. To the coupling ineniher ot the phonograph is detachably seeured in the usual manner, a eot'iperatingeoupling ineinher 20. which will ot' course vary in style to tit the particular' iuaehine employed. 'lhe tulie :21, which is integral with or secured to the inemlier Q0. is tittedv snugly within the end o1" a long' coiled tuhe pi'eferahly inade ot ruhberfunder whiehv teri'n l include ruhher coated t'ahrie. asordinary hose pipe. .Xs Shown. the coil eonsists oi a plurality ot' turnsot equal diameter and ot' a size to eneirele. the phonograph oi' like instrument. the ends of the coil extending` tangentially. one to engage with the coupling' deviee. the other witha horn. as herea'ttei' deserihed.

less than one ineh interior dianieter and lt'i l l liavet'ouiul it advantageous to make this tuhe of not" feet long. the length ot' the lowest C elosed diapason pipe .ot an organ.` though tuhes ot S. l or 2 multiple ol feet` possess certain advantages. 'l have also found` that the resonating or sound earrying Capacity ot the ruhtorni a portion 2 ot redueed diameter.`

over which is seeiired a short tuheJ-Zt' ot thin tlexihle material, as loldheaters akin, wliieh projeets beyond the end-ot tl'ietuhe QQ. Secured over this tangential end 2t-fof tent. or indeed of any To this end, l prefi the tuhe 22 is a metal sleeve 27, whie-l'i also projects lieyond *the endet the tulie'; lhut not. so tar as does-the tlexihle tutie QG;A which hy reason oi" the reduction ot the tulie 22, and the consequent annular space 1oetween the parts 26 and Q7. almost its entire length. See Fig. 4. A telescopic sleeve which has a snug sliding tit ron the Sleeve Q7. is integral with or Se.

curely connected to the snialler or throat end 29 of conieal horn 3,0. the body per tion 31 oic which is 'best made of copper.

is Atree to vibratie for while the sleeve 2S is preferably made of sheet brass, or other metal or alloy. On the sleeve 27 is a series of marks 32 formingl a gradtuated scale for conveniently adjusting orlareadjusting the longitudinal relations ol' the tube 22 and the horn 30, see Fig. 2.

A considerable portion of the forward or mouth end of the horn body 31, is cut away, or omitted in making, as shown in Figs. 1', 2, 3 and A4, and a stout circular metal hoop 33, the arc of which corresponds to that of the remaining metal segment, is rigidly secured to the end thereof. The partially fiaring conical shape of the horn is restored or completed by means of a segment or gusset of parchment, vellum or like material 34, which is tightly stretched and secured to the free part of the hoop 33 and to the edges 36 of the body 31 of the horn. I preferably secure the segment 34 at the edges ofY the body 31 by means of flat/bars 37 and a curved plate 38,'between which and the body 31 the parchment is engaged, the parts 37, 38 being held to the body by'small bolts 39 playing in slots 40 in the body 31. yBy the use of these elongated slots 40, l am enabled at any time to take up any Slack or wrinkles which may occur in the segment 34.

lVithin the metal body portion of the horn BO, and preferably at the rear of the flexible segment or gusset 34, l rigidly 'secure a lblock 41 of metal, which supports one or more vibrating gongs 42. l. prefer to employ al harmonic series, in the present instance an octave, of such'gongs,.which may be of desired form, preferably coiled bars, such as are used in cathedral clocks, sec Figs. 2 and 4.

As shown in Figs. l and the..horn 30 is supported at its throat end by the bracket 19,. in which the sleeve 28 slides, and at its mouth end by a telescopic rod 43 detachably engaged with the rod or standard 17 and carryingat its free end a chain or cord 44 connected to a loop 45 secured to the upper side of the horn. In practice I find it advantageous to make the horn without the usual flaringr metal portion at the vmonth end, z'. c., with an approximately continuous taper from end toend except as to the parchment portion.

'ln Fig. 5 of t e drawings, l have shown an additional device which l may employ in order to still further amplify the sound. lt consists of a tapered tube 46 within the coupling tube 21 and with its smaller end secured to the member Q0 so as to register with the aperture therein. The tube 46 may be tapered throughout its length, as shown, or at least at its free end, which is snugly embraced by the tube 21, the tubes 21 and 46 being thus held in concentric relation.

It Will be seen that my device in its entirety constitutes what may be called an orchestraphone, that is a sound purifying, resonati-ng and tonalifying device adapted to reproduce tones of every pitch and timbre, so that it is particularly adapted to music originally produced by anorchestra, containing instruments of various sorts. This adaptation is achieved by the use of the long semi-flexible tube through which the sounds pass an'd in which scratchingl and like disagreeable noises appear to be taken up; by the employment of a great variety of vibrating substances, from the light vand delicate membrane 2o to the heavy gongs 42, which are acted upon and seem-to accentuate notes at different points of the scale; and by the adjustability of theu horn 30. by which the men'ibrane 2Gl may be held within the sleeve poition Q8 ot the horn or thrust forward a considerable distance into thc throat end of the horn itself.

As already stated, the ditl'erent features of my device as described act cumulatively. so that substantial gains in tone power and sweetness may he obtained cvcn where certain of them are omitted. llence, l do not wish to be limited to the use of the entire con'lbination shown, or otherwise except as set forth in the claims. lt is also clear that many mechanical changes may be made in my device without departing from lhe spirit of my invention., Thus. the vertical arrangement of the coiled tube. the provision 'tor separating the stand, coil,horn, etc.,"t`or packing and for their easy reassembling, and

other features of the sort, are within4 the province of the mechanic.

lt will be understood that my device may be used in producing records as well as in sound reproduction, and that the. phrase sound an'iplifying` device7 is used in the claims in its broad sense, as includingr any modification of the tone. rlhe phrase talklll() ing machine is also used in certain of the claims in itsbroad sense to include any machine for the prodnctionor reproduction of sound records.
